Saw this on HM forum & thought this is a neat application. Maybe for custom panels or restoring old machines with rubbed off face plates. I've seen some etching examples when trying to restore the original plates, but it looks labor intensive. In 3DP you can do all the layout, font, sizing, background (maybe even curvature?) in CAD & the end result looks kind of snappy. Some more examples in the post.
